Title: Improvements in or relating to high-speed photographic cameras
IPC: G03B39/02
Filed: 1944-06-21
Abstract: 582,637. Photographic high-speed cameras. SCOPHONY, Ltd., and STEVENS, E. W. June 21, 1944, No. 11824. [Class 97 (i)] A photographic camera includes means for holding stationary a carrier having a lightsensitized surface, and a continuously rotatable optical system which is adapted to -displace every entering light ray parallel to itself and which co-operates with a stationary system of image-forming elements to form successive images in spaced relationship on the light-sensitized surface. The rotatable optical system may consist of two parallel reflectors adapted to rotate about an axis passing obliquely through one of them. The stationary system may consist of or include a ring of lenses, and may include a collimating lens coaxial with the axis of rotation of the rotatable system. A reflector may be associated with each image-forming element so as to form the images on a convex or concave cylindrical lightsensitized surface. The camera may include a drum arranged to carry in its interior two spools carrying a light-sensitive film, part of the length of which is wrapped round the exterior of the drum. As shown, a stationary drum 10 carries a length of film 11 wrapped round its periphery to form a cylindrical ring. Film spools may be provided inside the drum and the film drawn off through one or more slits in the drum periphery. Fifty lenses 12 are distributed round a stationary support with their axes equidistant from and parallel to the drum axis (the camera axis). Fifty right-angle reflecting prisms 13 are placed respectively behind the lenses 12 and surrounding the drum 10. The balanced rotor 14 rotatable about the camera axis has two plane reflectors 15, 16 which reflect light passing through a collimating lens 18 and shutter 17 through the lenses 12. The rotor is directly connected to a variablespeed electric motor 19 and may attain a speed of 12,000 r.p.m. A right-angle reflector may be placed in front of the lens 18 so that the camera can be operated with its axis vertical when taking horizontally. After the rotor has run up to speed, the shutter is operated by means responsive to the beginning of the event to be photographed, and the shutter is closed as the rotor returns to the position it occupied when the shutter opened. Fixed partitions may be provided between the prisms 13 and the film drum 10 to prevent light emerging from any one lens 12 from entering the fields of the adjacent lenses. The varying orientation of the images may be rectified in printing, or by an optical device such as a Dore prism in viewing. The images may be projected by an arrangement similar to the camera, the drum being internally illuminated, and a projection lens being arranged in the axis of rotation. The projection lens may be replaced by a telescope and used as a viewing device. Large aperture lenses, e.g. F. 2.5, with a narrow slit in front of each, may be used with a narrow mirror 16.

Title: Brueninghaus hydraulik gmbh control apparatus for controllabel hydraulic pump/motor drive
IPC: F16H61/46
Filed: 1973-03-12
Abstract: 1428162 Hydrostatic transmission control O & K ORENSTEIN & KOPPEL AG and BRUENINGHAUS HYDRAULIK GmbH 12 March 1973 [21 July 1972] 11879/73 Heading F2W In a hydrostatic transmission for a vehicle wherein a variable displacement pump 2, which may be of the axial piston type, supplies pressure fluid to a motor 21, the pump displacement is varied by an actuator 12, supplied with pressure from a pump 3 whose delivery is dependent on the speed of the engine 1 and the output pressure from which, in a pipe 6, is limited by a pressure limiting valve 13, a throttle valve 19 and a throttle valve 22 both of which are adjustable, the former by the main line pressure from pump 2 via a shuttle valve 31 and the latter by the actuator 24 for service brakes. The control pressure in pipe 6 passes to the actuator 12 via a reversing valve 8 and throttle valves 25. A throttle valve 5 provides the resistance to the output of pump 3 to maintain the pressure in line 6. In operation the rise in pressure in the pipe 6 due to increase of engine 1 speed causes the pump 2 to be adjusted to its maximum displacement on the engine speed reaching a predetermined value above idling speed, and the pressure in pipe 6 is maintained at the value which achieves this by valve 13. Further increase of speed is by variation of engine speed. On increase of the pressure in the main circuit 30 above a predetermined value the pressure acts via pipe 20 to open throttle valve 19 and thereby cause the pump 2 to be adjusted towards neutral to decrease the load on engine 1. When the service brake control 24 is actuated this opens throttle 22 to decrease pump displacement, and consequently this control can be used for inching of the vehicle (which may be a fork lift truck). The valve 8 can be electrically operated. The provision of springs 11 to bias actuator 12 to the neutral position ensures that motor 21 is hydrostatically locked when the vehicle is stationary (and engine 1 switched off).

Title: Improvements in or relating to a method and apparatus for counting breakages in groups of filaments
IPC: G01N3/06
Filed: 1966-03-18
Abstract: 1,136,312. Counting breakages on multifilament fibre. INSTITUT TEXTILE DE FRANCE. 18 March, 1966 [20 March, 1965], No. 11910/66. Heading G4H. As a break occurs in a group of filaments e.g. fibres, when clamps holding the fibres are moved apart a series of impulses are produced in one of the clamps which are converted into electrical signals and the number of series of impulses recorded. In the embodiment described the impulse pickup consists of a microphone having a magnet with a fixed coil and a diaphragm between the magnet and the clamp. The impulse pickup delivers a damped sine wave signal via an amplifier and threshold device through an inverter and shaper where it is converted into a negative pulse. This is then converted into a short square wave signal which controls a counter or graph recorder. The apparatus may be used for measuring the strength of linen material or tyres.

Title: Process for the preparation of new n-substituted camphoric amides
IPC: C07C233/12
Filed: 1936-04-27
Abstract: Camphoric acid bis-dialkylamides are prepared by reacting the dichloride of a camphoric acid or the chloride of a monodialkylamide of a camphoric acid with a dialkyl amine.  The products possess therapeutic properties.  According to the examples: (1) d-camphoric acid is treated with phosphorus pentachloride and the resulting mixture of d-camphoric and l-isocamphoric acid dichlorides then reacted with diethylamine to give a mixture of the bis-diethylamides of the same acids, from which the d-camphoric acid bis-diethylamide may be isolated by crystallization from ligroin; when l-camphoric acid is used as starting material, a mixture of the bis-diethylamides of l-camphoric and d-isocamphoric acids is obtained, from which the l-camphoric acid derivative may be separated; (2) l-isocamphoric acid chloride is converted by interaction with diethylamine into its bis-diethylamide; (3) d-camphoric acid is treated at ordinary temperature with phosphorus pentachloride and the d-camphoryl chloride so prepared is reacted with diethylamine to form the bis-diethylamide; in a similar way the bis-dimethylamide, -dibutylamide, -diamylamide and -methylethylamide of d-camphoric acid may be obtained; (4) d-camphoric acid monodiethylamide is heated with thionyl chloride and the product added in small quantities to a benzene solution of diethylamine to produce the bis-diethylamide of l-camphoric acid; by using dimethylamine the a -diethylamide-b -dimethylamide is obtained, and by using methylethylamine the a -diethylamide-b -methylethylamide results; (5) d-camphoric acid a -dimethylamide is treated with thionyl chloride and then with diethylamine whereby the a -dimethylamide-b -diethylamide is produced; when dimethylamine is used the bis-dimethylamide is obtained.

Title: Method of correcting the shape of a boundary surface of an optical device
IPC: B23K26/02
Filed: 1964-03-23
Abstract: 1,021,839. Etching. INSTITUT FUR PLASMAPHYSIK G.m.b.H. March 23, 1964 [March 22, 1963], No. 12110/64. Heading B6J. [Also in Divisions G2 and H3] The boundary surface of a laser crystal 10<SP>1</SP>, Fig. 3, or other optical element is corrected to make it correspond more closely to the equiphase surface of a wave front passing therethrough by producing an image at 26 of the uncorrected surface showing the phase errors in the form of intensity variations of the image, projecting this image back on to layer 20 bounding the surface and made of a material whose solubility characteristics in a specific solvent can be varied by irradiation with the light used for the back projection, and, using this irradiated layer as a control, selectively removing material from the uncorrected boundary surface so as to obtain a surface corresponding more closely with the equiphase surface of the wavefront. As applied to a ruby crystal 10<SP>1</SP>, the end faces are ground substantially plane-parallel to one another and coated with a 100% reflective mirror 16 at one end and a transparent layer 20, of a material whose solubility in certain solvents alters under irradiation by short wave light, but is insensitive to the red light emitted by the laser, and, after layer 20 is ground flat at 22 a 95 to 99% reflective non-absorptive mirror coating 18<SP>1</SP>. The crystal 10<SP>1</SP> is excited to produce stimulated emission and through optical system 24 produces an image on the red-sensitive photographic layer 26. The mirror coating 18<SP>1</SP> is removed and photographic layer 26 developed and fixed. Light, to which layer 20 is sensitive, is now used to project an image of developed layer 26 back on to layer 20 which is then treated with a solvent so that layer 20, which is used as one face of the laser crystal, has a boundary surface more closely correspondingwith the equiphase surface. A coating similar to 18<SP>1</SP> is then provided on the new surface. In a modification the production of the image and back projection are repeated several times to obtain a boundary surface successively closer to that required. In a further form, layer 20 does not remain in the optical element but is used as an etch-resistant layer for controlling the direct etching away of the element and the layer is subsequently removed.

Abstract: 611,135. Watches. McMILLEN, D. A. April 23, 1946, No. 12199. Convention date, July 27, 1945. [Class 139] A watch has a main dial M indicating hours and minutes, hour and minute hands D and E and means for setting said hands which includes a main seconds hand C, a rotatable dial marked with a sixty-second scale B and lockable in an adjusted position, an auxiliary seconds hand H geared to an auxiliary minute hand K which moves over a subsidiary dial through one minute graduations of a scale J thereon for each complete revolution of the auxiliary seconds hand H, the auxiliary seconds and minute hand being controlled by stop-watch mechanism of known type. The watch is particularly for use by an aeroplane navigator to determine the exact time of making a celestial observation. The watch is set to the correct time by rotating the scale B, by means of a crown A in its extended position, until the zero coincides with the seconds hand C. The crown A is pushed in to lock the scale B in its adjusted position and rotation of the crown A coupled with depression and rotation of a knob F will serve to adjust the minute and hour hands E and D. When making his observation the navigator depresses a knob G to start the auxiliary hands K and H rotating. Any suitable time later the navigator, by subtracting the number of minutes and seconds indicated by the hands K and H respectively from the time indicated by the hands C, D and E, can determine the exact time of making the celestial observation. If desired the auxiliary seconds hand may be offset from the main arbor and move over a separate dial as shown in dotted lines.
